Patent DE-3112177-A1 (DE)
Title: Shaping tool, in particular a deep-drawing tool
Inventor: KUUSISTO MATTI JUHANI
IPC: B21D22/22
Filed: 1981-03-27
Abstract: The invention relates to a shaping tool with a drawing die forming a shaping part, a holder disc holding the sheet-metal blank to be shaped against the drawing dies, and guide pillars fixed to one die, along which the other die can be displaced in sliding fashion. The die which is displaceable relative to the pillars is locked to the pillars by a locking mechanism when the drawing die and the holder disc are resting against one another but releases the locking when the said die is being displaced relative to the pillars. By this means, the force with which the sheet-metal blank is pressed against the drawing die by the holder disc during drawing is transmitted to the pillars and the drawing force of the press available for the shaping of the sheet-metal blank is not reduced.

Title: Upholstered furniture
IPC: A47C31/02
Filed: 1981-04-06
Abstract: In an item of upholstered furniture which can be used selectively as a bed or seat, the surrounding construction consisting of a plurality of boards is to be joined together by attachment elements, the intention being for the boards to be upholstered and provided with covers. The attachment elements consist of mounting angles which are held by screws, are reinforced by transverse deformations and connect the boards to one another, while the covers receiving the cushions are fitted at their edges with insertion members which interact with groove-like depressions which are worked into the boards in the attachment regions. As a result, the assembly of the surrounding construction is simplified and the upholstery or covering of the boards is improved. In order to prevent undesired emergence of the insertion members from the groove-like depressions, said groove-like depressions form different angles with the surfaces of the boards. The insertion members advantageously consist of spring-like plastic strips which are bonded or sewn firmly at the edges of the covers.

Patent DE-3205790-A1 (DE)
Title: Control electronics of a metering dispenser for cleaning agents
Inventor: SCHMERDER WOLFGANG
IPC: A47L15/42
Filed: 1982-02-18
Abstract: Control electronics for adjusting and keeping constant the cleaner concentration in an aqueous solution having the property that the electronics can be adapted to different cleaners and the control range is maintained irrespective of the type of cleaner used. The conductivity sensor is operated from a stabilised alternating voltage via a matching network. In the case of normal dispensing, the matching potentiometer R2 is set in such a manner that the direct-voltage drop across R5 (actual value) is identical with the voltage drop across R9 at centre position (nominal value). If the cleaner concentration drops, the actual value rises. If this exceeds the nominal value set, the Schmitt trigger is triggered and causes cleaner to be supplied until actual value and nominal value correspond to one another again. Since the circuit R2 has been calibrated at centre position of R9, the switching threshold of the Schmitt trigger can be moved towards higher and lower values. This enables the respective cleaner concentration to be adjusted to any value. Once the value has been set it is always kept constant by the electronics. <IMAGE>

Patent DE-3206286-A1 (DE)
Title: Spherical-piston device for engines/machines
Inventor: SZIRMAY ZOLTAN DIPL ING
IPC: F01C3/02
Filed: 1982-02-22
Abstract: The invention relates to a spherical-piston device for engines/machines having elements which bound chambers, which execute a tumbling movement relative to one another and of which one is designed as a housing construction and the other is designed as a piston. The mutually displacing mating surfaces of the housing construction and of the piston are designed as spherical surfaces. The interior of the housing is divided into chambers by vanes, the centre plane of which contains the axis of the housing. The vanes are inserted into recesses in the piston disc, the movement-compensation units ensuring the sealed mechanical connection between these two elements. The movement-compensation units are of fork-like design, the fork prongs surrounding the vanes and being mounted rotatably in the recesses on the piston disc. The design of the movement-compensation unit differs depending on the number of vanes. If there are more than two vanes, then - by rotation in the movement-compensation unit - the axis of the rotary fork surrounding the vanes rotates in a plane perpendicular to the axis of the piston disc. As a result, the respective angle between the axes of two adjacent rotary forks changes and the piston executes a tumbling movement.

Title: Method and installation for separating coarse and fibrous materials from contaminated water
Inventor: MENGES MARTIN DIPL ING
IPC: E03F5/14
Filed: 1982-05-13
Abstract: The method for separating coarse and fibrous material from contaminated water is characterised in that it can be incorporated in a trouble-free manner into a water course and the water is reliably freed from the said harmful materials. The retained coarse and fibrous materials are freed of faecal matter owing to the special nature of the washing process. The coarse and fibrous materials purified in this way are fed by the flow to the discharge coil, in which they are then conveyed upwards and dewatered. The dewatering is carried out in such a way that the press water can be fed directly to the water course flowing off. The material pressed and conveyed upwards in this way is then brought into a transport pipe, from where it is supplied to a suitable storage site or a suitable tank.

Title: Labelling machine for moulded bottles
IPC: B65C9/06
Filed: 1982-06-11
Abstract: The invention relates to a labelling machine for moulded bottles. Before the bottles, which are held by clamping elements so as to be non-rotatable, are moved past a labelling station by a turntable, they are aligned with respect to their rotational position. A shaped part, which is laterally movable towards the bottle and to which a counterholder is assigned on the opposite side, serves as alignment element. During the alignment the clamping elements are released. The alignment element forms a module together with a press-on element for the labels and is jointly movable with this mode. Just a common control in the form of a control cam is therefore necessary for alignment and pressing-on.
